The voltage between the emitter and the base is 5 volts in 2N2222 and 6 volts in BC547. The collector to base voltage at 2N2222 is 60 volts, whereas it is 50 volts at BC547, and the collector to emitter voltage is 30 volts at 2N2222 vs 45 volts at BC547. The 2N2222 has an emitter, base, and collector pinout, whereas the BC547 has a collector, base, and emitter pinout. If you want a higher current, the TIP3055 can. If you need more than 1 amp at the output, you can use a Darlington transistor like the TIP122, which can take up to 5 amps of amplified current. The 2N2222 is the one to choose if you require more than 200mA but not more than 1A. The BC547 transistor came in a to-92 package, but 2N2222 transistors, such as the PN2222 and KN2222, also came in to-92 packages. The 2N3904 or 2N2222 will suffice if you require less than 200mA. The 2N transistors were packaged in a to-18 package, which means they were enclosed with metal. The 2N2222 transistor is more powerful than the BC547. 2N3906 is complementary to 2N3904 NPN bipolar junction transistor. Collector to Emitter Voltage (VCE) is 30V. ![]() The useful dynamic range extends to 100 mA as a switch and to 100 MHz as an amplifier. So in this way, the 2N2222 does have superiority in that it can handle greater current. A 2N2222 can handle up to 5 times that amount, since it can handle up to 1A (ampere) of current flow from the emitter to collector to power on a load. Collector to Base voltage ( VCB ) is 50V 2N3904 MMBT3904 PZT3904 NPN General Purpose Amplifier This device is designed as a general purpose amplifier and switch. A 2N3904 can handle up to 200mA (milliamperes) of current flow from the emitter to collector terminal.Collector to Emitter Voltage (VCE) is 45V.DC Current Gain range is 110 to 800 hFE.The maximum frequency on this frequency is 250MHZ, which is the 2N2222 transistor's transition frequency. to the sum 01 2N3904 02 2N3906 Loyros alin R1 Load mm ov In ( -ve ) Figure 12.28. The trigger terminal's maximum bias voltage is 200 mV, while the 2N2222 transistor's maximum bias current is 200 mA. In ( + ve ) Load R1 Link Alin 02 2N3904 2N3904 mm ov Figure 12.27. The maximum collector current of the 2N2222 transistor is 800mA this is the greatest current that this device can handle. The maximum current gain of the 2N2222 transistor is 300hFE, and this number determines the transistor's amplification factor. A bipolar NPN transistor, the 2N2222 is a transistor with two poles. ![]()
